Description
CROSS-REFERENCE TO RELATED APPLICATION(S)
[0001] The present invention claims priority of Korean Patent
Application Nos. 10-2010-0132060, filed on Dec. 22, 2010, which is
incorporated herein by reference.
FIELD OF THE INVENTION
[0002] The present invention relates to building management and
operation technology, and more particularly, to an apparatus and
method for collecting building management data generated from
individual buildings, and converting the collected building
management data into the format of common data.
BACKGROUND OF THE INVENTION
[0003] Recently, with the climate change convention, a variety of
low-carbon based energy reduction policies have been promoted by
various countries, and a variety of energy reduction technologies
have been researched in a field of building management which takes
a large part in energy consumption. The research on technologies
for energy reduction of buildings is developed toward passive
reduction technology and active reduction technology. The passive
reduction technology is aimed at environment-friendly and
high-efficiency structures and materials of buildings, and the
active reduction technology is focused on replacement of low-power
facility in buildings and optimal management of the buildings.
[0004] Particularly, in the active energy reduction technology for
buildings, research is being actively conducted on building
automation which is focused on the existing functions of the
buildings. Furthermore, research is being also actively conducted
on a building energy management system (BEMS) technology for
managing a building in point of energy, escaping from the existing
building management technology. However, the technologies of the
BEMS require getting an expert consulting for analyzing individual
buildings and developing an optimal building management, which
entails a lot of cost and time. Moreover, it is difficult to draw
voluntary participations from building owners.
[0005] In order to overcome such problems, research is being
conducted on an integrated management system for buildings based on
a remote control system by a small number of BEMS management
experts. However, when integrated control systems are constructed,
there are many difficulties in constructing and managing the
integrated control systems because of the different building
management environments such as individual control networks and
non-compatibility between the systems due to different
manufacturers.
[0006] In order to introduce the optimal management system for
energy reduction into a large number of buildings, it is
necessarily needed the development of a remote control ystem based
on low cost and high efficiency. Through the remote control system,
an optimal management plan for integrally managing various
buildings and reducing energy may be derived.
[0007] However, it is difficult to integrally and consistently
analyze building management data and derive an optimal management
plan for individual buildings which are managed under a variety of
building management environments such as heterogeneous building
automation systems (BAS) and building energy management systems
(BEMS). Furthermore, since separate analysis and derivation for
each building are required, the efficiency of the remote control
system decreases, and the management cost inevitably increases.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0042] Hereinafter, embodiments of the present invention will be
described in detail with reference to the accompanying drawings so
that they can be readily implemented by those skilled in the
art.
[0043] FIG. 1 is a block diagram of a remote building control
system in accordance with an embodiment of the present
invention.
[0044] Referring to FIG. 1, the remote building control system
includes a plurality of data collection clients 120 and a remote
control server 140. The data collection clients 120 are installed
in individual buildings 100 and configured to collect building
management data generated from the individual buildings 100,
respectively. The data collection clients 120 and the remote
control server 140 may be implemented as a client-server
environment with a network 130 such as the wired/wireless
Internet.
[0045] Specifically, each of the data collection clients 120 is
installed in a corresponding building 100 to be subjected to a
building management, and collects building management data 110
generated from the corresponding building.
[0046] The building management data 110 may include BAS management
data of the building 100 and a variety of sensing data on
temperature, humidity, CO.sub.2, power consumption, and gas
consumption. The building management data 110 collected by the data
collection client 120 are transmitted to the remote control server
140 through the network.
[0047] The remote control server 140 receives and stores the
information collection client 110 from the respective data
collection clients 120 in a database (DB) 150.
[0048] Alternatively, the information collection client 110 from
the respective data collection clients 120 may be provided to a
server for security and/or management measure establishment.
[0049] Before transmitting the information collection client 110
from the respective data collection clients 120, the data
collection clients 120 convert the information collection client
110 into the form of common building data for constructing a common
management environment of the buildings to generate a common
communication layer (CCL) message to be transmitted to the remote
control server 140. Through this operation, the remote control
server 140 may standardize the management methods of the respective
buildings while guaranteeing compatibility the building management
data generated from the respective buildings, and consistently
process the building management data.
[0050] Alternatively, the data collection client 120 may be
configured to generate a CCCL message by a separate CCCL message
generator.
[0051] FIG. 2 illustrates the operation in which a data collection
client shown in FIG. 1 collects generated from the building
management data.
[0052] Referring to FIG. 2, the data collection client 120 includes
a variety of central control & monitoring systems (CCMS) 220,
222, 224, 226, and 228 for separate facilities and sensors in the
building 100. The CCMSs 220 to 228 collect the BAS management data
generated from BAS facilities 210, 212, 214, and 216 and the
sensing data sensed by environment sensors 218. The CCMSs 220 to
228 include an air conditioning CCMS 220, a power CCMS 222, an
illumination CCMS 224, a security CCMS 226, and a sensor CCMS 228.
The air conditioning CCMS 220 receives information generated from
an air conditioning facility 210. The power CCMS 222 receives
information generated from a power facility 212. The illumination
CCMS 224 receives information generated from an illumination
facility 214. The security CCMS 226 receives information generated
from a security facility 216. The sensor CCMS 228 receives sensing
data sensed by various environment sensors 218.
[0053] As illustrated in FIG. 2, the CCMSs 220 to 228 may be
separately provided or integrated in one CCMS.
[0054] The communication between the various facilities and sensors
210 to 218 and the CCMSs 220 to 228 may be performed through a
control and communication protocol such as BACnet, MODbus,
LonWorks, TCP/IP, Zigbee, Serial COM, Bluetooth, or UWB, but is not
limited thereto. Furthermore, as will be described with reference
to FIG. 3, the respective CCMSs 220 to 228 converts the building
management data 110 to a CCL message 230 with a combined form of
data and an object generating the data through the use of a CCL
message generator 230, which will then be transmitted to the remote
control server 140.
[0055] The data collection client 120 further includes an object
filter 250. The object filter 250 sorts out the building management
data which are to be transmitted to the remote control server 140,
based on a monitoring reference table 240 provided from the remote
control server 140. More specifically, the object filter 250
collects necessary building management data and discards
unnecessary building management data by referring to the monitoring
reference table 240. The necessary building management data
includes building management data generated from a facility
indicated by `O` in the monitoring reference table 240 or building
management data collected by a CCMS corresponding to the facility,
and the unnecessary building management data includes building
management data generated from a facility indicated by `X` in the
monitoring reference table 240.
[0056] FIG. 3 illustrates the operation of the CCL message
generator in the data collection client 110 shown in FIG. 1.
[0057] Referring to FIG. 3, the data collection client 120 further
includes a CCL message generator 320 configured to convert building
management data 340 having passed through the object filter 250
into a CCL message 350. The CCL message has a structure which may
be effectively utilized for monitoring and analyzing the building
management data 340 by defining it in a common message type.
[0058] The CCL message generator 320 collects the building
management data 340, monitoring time 330, and the data of the
monitoring reference table 240, and converts the collected data
into the CCL message 350 such that the remote control server 140
facilitates the storage and analysis of the building management
data. For example, the BAS building management data 340 represented
in the form of <object, value> is converted into the form of
<building #, CCMS, protocol, object, position, time, value>
including the meanings of <building ID, facility type, facility
control protocol, object, positional information of object,
information collection time, and sensing value or state value of
object>.
[0059] FIG. 4 is a flow chart illustrating a method performed by a
remote building control system in accordance with the embodiment of
the present invention.
[0060] Referring to FIG. 4, the remote control server 140 performs
initialization of the remote building control system at step S402,
and performs a client searching to initialize building management
data collected from one or more buildings to be subjected to a
building management and the data collection clients of the
buildings at step S404.
[0061] At step S406, the remote control server 140 broadcasts a
client search message to the data collection client 120 for each of
the buildings. At step S408, in response to the client search
message, the data collection client 120 unicasts a client response
message, for example, a keep alive message to the remote control
server 140, in order to inform the remote control server 140 that
preparation was completed. The client search message is broadcast
to the data collection clients 120 from the remote control server
140, while the client response messages of the data collection
clients 120 are unicast to the remote control server 140.
[0062] Thereafter, at step S410, the remote control server 140
transmits in a broadcast mode a monitoring reference table 240 to
the data collection clients 120 which are recognized to be in the
preparation state.
[0063] At step S412, the data collection client 120 transmits in a
unicast mode a message requesting a report of building management
data to the CCMSs 220 to 228. At step S414, the respective CCMSs
220 to 228 send in a broadcast mode a data reporting message
containing the building management data to the data collection
client 120.
[0064] After that, the data collection client 120 receives the data
reporting message from the CCMSs 220 to 228, and filters the
building management data through the object filter 250. At step
S416, the building management data 340 filtered by the data
collection client 120 is converted into a CCL message
representative of building management data before transmitting to
the remote control server 140.
[0065] Therefore, the remote control server 140 may construct a
common management environment, and standardize the management
method for buildings.
[0066] In accordance with the embodiment of the present invention,
individual buildings based on the existing BAS/BEMS may interwork
with the remote control system only by connecting the data
collection clients, while maintaining the management environments
of the buildings.
[0067] Furthermore, it is possible to provide an efficient
collection for building management data through the filtering using
the monitoring reference table for mass transmission of the
building management data and effective data analysis.
[0068] While the invention has been shown and described with
respect to the preferred embodiments, it will be understood by
those skilled in the art that various changes and modifications may
be made without departing from the scope of the invention as
defined in the following claims.
